XFX power supplies are made by Seasonic, no worries there. The wattage is excessive though, 850W is more than enough even to run a pair of 7970s in SLI.
I would also say that unless you are into some REALLY intensive video rendering / CAD, the Sandy Bridge E is probably a huge waste of money and you would probably be very happy with an i7 3770k instead. I would personally take the cash saved on that and drop it into upgrading the GPUs to 7970s instead of 7950s and maybe an even bigger SSD for storing all your video data. I think that would probably improve your experience more noticeably.
Should I go for the xfx xxx edition 850w then? however it is only a 80+ Silver, even though silver and gold doesn't really make much different, but it always feel better with gold/platinum, as other parts in the build is pretty much the top end as well. Also if I am not mistaken under 20% load, the psu will be using passive cooling with the fan off, which I presume would be much more quiet, and under 20% load would be easier with a 1050W than 850W, also 1050W seems more future proof. That's what I think anyway.

About the z77 platform, one of the reason I chose x79 is really because of the Rampage Iv extreme being very..perfect to me. I love the rampage Iv extreme, the color, name, 8 ram slots, 4 pci slots, OC keys, all the features and everything of this board. Which also seems slightly more future proof than the others. Originally I wasn't planing to get the asus directcu ii, but other 2 slots card which I could possibly trifire/quadfire if it brings good performance by the time I need. ( Of course they are not atm, but by the time I need more performance there is always one more option between replacing by new series cards or trifire) Although now that I have decided on the "fat" 3 slots Asus cards, which can only be 2 way crossfire max (if I am not mistaken).
Anyway the point is, if I am going for the z77 board, I would probably go for the maximus V extreme. Which I know doesn't seems necessary, but that is the one that I would like to have ( 4 pci slots, OC key etc ). And the maximus is basically the same price as the rampage. So it seems to be better getting the x79 for its performance and future upgrade option.
I am sure I will be happy with z77 too, but I have worked out that x79 with 3930k +Rampage IV extreme is about 300 more compare to Z77 with 3770k+Maximus V extreme, of course I could go for the 3820 too for the exact same price as the z77, but 3930k just seems a better option for x79, easier to be sold when Ivybridge-E comes out too. Even if I am not upgrading to Ivybridge-E, 3930k still seems to be a good cpu to hold on to.
Thanks a lot for your reply too, to be very honest with you, I did have a really tough time choosing between x79 and z77. And now it kind of come back again even after I have decided to have x79 lol
As for the graphic card, 7970 just doesn't seem to be worth the extra money to me (over a 7950), also I am kind of having the plan of getting the 8000 or 9000 series already, run the 7950 til I think they should be replaced.
What I am trying to say is, the 7970 of course is the best and the top of the world now, and that would bring me slightly more significant improvement over a 7950 compare to the improvement between 3770k and 3930k.
However I can sort of feel that by the time my 7950 should be replaced, 7970 wouldn't be far from it, perhaps the same time.
Also when I looked back to the 6970, the 7950 is easily faster than it. Therefore I presume if I get a pair of 7970 now, a much cheaper pair of 8950 in few months time would easily beat my 7970s. Of course next gen cards would always be faster, but 7970 is about 160 more than 7950 now per card, and let's say if I am planning to get the 8950 or 9950 by the time, I have really wasted the 160 per card.
You could say that would apply to the cpu too, but IMO cpu improvement between generations is much more slower and unnecessary, which is why x58 still a pretty good and fast platform with good CPUs.
I hope you all can understand what I think of the platform.
I will consider your opinions too. Thanks for replying.
